Abstract
When ion bombarded at room temperature, the surface of the icosahedral quas icrystal Al70Pd20Mn10 converts to a cubic structure. Bombarded at elevated temperatures, the surface remains quasicrystalline but converts to a tenfol d-symmetric structure, In this paper, we search for a change in the electro nic properties as the structure is modified and argue a case against the Hu me-Rothery rule for these alloys.
